CVE-2025-10909 is a cross-site scripting (XSS) vulnerability identified in Mangati NovoSGA versions up to 2.2.9. The vulnerability resides in an unspecified function within the /admin path of the SVG File Handler component, specifically involving the manipulation of the 'logoNavbar' and 'logoLogin' arguments. An attacker can craft malicious input to these parameters, which is then improperly sanitized or validated, allowing the injection and execution of arbitrary JavaScript code in the context of the affected web application. This flaw enables remote exploitation without requiring authentication, although user interaction is necessary to trigger the malicious script execution. The vulnerability has a CVSS 4.8 (medium) score, indicating moderate severity. The vendor was notified but has not responded or provided a patch, and a public exploit has been released, increasing the risk of exploitation. The attack vector is network-based with low attack complexity, no privileges required, but user interaction is needed. The impact primarily affects confidentiality and integrity at a limited level, with no direct availability impact. The vulnerability could be leveraged to steal session cookies, perform actions on behalf of authenticated users, or conduct phishing attacks within the administrative interface of NovoSGA, a system likely used for administrative or management purposes. Given the lack of vendor response and public exploit availability, this vulnerability poses a tangible risk to organizations using affected versions of NovoSGA.

For European organizations using Mangati NovoSGA, this vulnerability could lead to unauthorized access to administrative sessions, data leakage, and potential manipulation of administrative functions. Since NovoSGA is an administrative system, exploitation could compromise sensitive organizational data or disrupt administrative workflows. The XSS flaw could be used to hijack sessions of administrators, enabling attackers to escalate privileges or pivot to other internal systems. The presence of a public exploit increases the likelihood of targeted attacks, especially against organizations that have not updated or mitigated the vulnerability. This risk is heightened in sectors with stringent data protection regulations such as GDPR, where data breaches could result in significant legal and financial penalties. Additionally, the lack of vendor support complicates remediation efforts, potentially prolonging exposure. Organizations relying on NovoSGA for critical administrative functions may face operational disruptions and reputational damage if exploited.

Given the absence of an official patch, European organizations should implement immediate compensating controls. These include: 1) Restricting access to the /admin interface of NovoSGA via network segmentation and firewall rules to limit exposure only to trusted IP addresses. 2) Employing Web Application Firewalls (WAFs) with custom rules to detect and block malicious payloads targeting the 'logoNavbar' and 'logoLogin' parameters. 3) Conducting thorough input validation and sanitization at the proxy or application gateway level if possible. 4) Monitoring web server logs and application logs for suspicious requests involving these parameters to detect exploitation attempts. 5) Educating administrators about the risk of phishing and social engineering attacks that could leverage this XSS vulnerability. 6) Planning for migration or replacement of NovoSGA if vendor support remains unavailable. 7) Regularly reviewing and updating incident response plans to address potential exploitation scenarios. These targeted mitigations go beyond generic advice by focusing on access control, detection, and compensating controls specific to the vulnerable component and parameters.
